ATTRACTION OF LUTZOMYIA LONGIPALPIS TO SYNTHETIC SEX-AGGREGATION PHEROMONE: EFFECT OF RELEASE RATE AND PROXIMITY OF ADJACENT PHEROMONE SOURCES.

Attraction of Lutzomyia longipalpis to synthetic sex-aggregation pheromone: Effect of release rate and proximity of adjacent pheromone sources.

In South America, the Protist parasite that causes visceral leishmaniasis, a potentially fatal human disease, is transmitted by blood-feeding female Lutzomyia longipalpis sand flies.A synthetic copy of the male Humidifiers produced sex-aggregation pheromone offers new opportunities for vector control applications.We have previously shown that the p

On the entry of an emerging arbovirus into host cells: Mayaro virus takes the highway to the cytoplasm through fusion with early endosomes and caveolae-derived vesicles

Mayaro virus (MAYV) is an emergent sylvatic alphavirus in South America, related to sporadic outbreaks of a chikungunya-like human febrile illness accompanied by severe arthralgia.Despite its high potential for urban emergence, MAYV is still an obscure virus with scarce information about its infection cycle, including the corresponding early events

Mycobacterium tuberculosis complex lipid virulence factors preserved in the 17,000-year-old skeleton of an extinct bison, Bison antiquus.

Tracing the evolution of ancient diseases depends on the availability and accessibility of suitable biomarkers in archaeological specimens.DNA is potentially information-rich but it depends on a favourable environment for preservation.In the case of the major mycobacterial pathogens, Mycobacterium tuberculosis and Mycobacterium leprae, robust lipid
